Basic Definitions It is an amazing fact that by adjoining the imaginary unit i to the real numbers we obtain a complete number field called `` The Complex Numbers." In this amazing number field every algebraic equation in z with complex coefficients has a solution. To prove this fact we need Liouville's Theorem, but to get started using complex numbers all we need are the following basic rules. Rules of Complex Arithmetic Every complex number has the ``Standard Form'' for some real a and b For real a and b Click on EXERCISES for some practice using these rules. Division Notice that rules 4 and 5 state that we can't get out of the complex numbers by adding (or subtracting) or multiplying two complex numbers together. What about dividing one complex number by another? Is the result another complex number? Let's ask the question in another way. If you are given four real numbers a b c and d , can you find two other real numbers x and y so that As an exercise in using rules 1 through 5, multiply both sides of the above equation by c di and then solve for x and y to prove that the answer to our question is yes.( Click on

Number Theory and Arithmetic geometry at Nottingham Click on to go to a new page Information for potential PhD students The group welcomes applications from potential PhD students. Successful applicants will be made an offer of a PhD place by the university. The funding opportunities for EU students include a postgraduate studentship (usually for three years) from EPSRC, which covers all university fees and (for UK students only) a maintenance grant. Alternatively, the school will help with applying to EU Marie Curie Fellowship which can provide support up to three years. In very strong cases, University Scholarships are available to successful candidates. With its large group of researchers working in a spread of related fields within Number Theory and Arithmetic Geometry, Nottingham is a most attractive place for PhD study. Currently the number theory group in Nottingham is the largest in the UK. Students who are at first not sure exactly in which area they wish to work can experience a wide variety of research topics before deciding, and always have the possibility of moving between supervisors.

Most of the papers and talks deal with the design and analysis of algorithms and data structures. They are grouped according to specific topic area, roughly in chronological order. The first section lists some general papers, such as my survey on external memory algorithms and data structures and my book Efficient Algorithms for MPEG Video Compression Click on whatever titles or topic areas interest you to get the papers you want. Some papers are listed in more than one topic area. For example, papers on I/O-efficient algorithms for geometric problems are listed in both the External Memory Algorithms section and the Computational Geometry section.

Math Path BAC is a simple and effective homeschooling system for teaching basic arithmetic to k-3 children. Brendan likes math! "Brendan is in kinder- garten this year (he is homeschooled) and your Math Path has become an integral part of our daily activities. It seems to be just what we needed! Thank you for your product and your genuine concern for teaching children their math facts. It is so Important, and your product is so simple and to the point." Sherri Brendan's mom Nashville, Tennessee The items described below are free. They are math related activities for pre-k children. Counting to 100 by 1's, 2's, 5's, and 10's This is an array of 100 circles, organized for easy counting by 1's, 2's, 5's, and 10's. Go slow on this. Don't ask a child who's not comfortable counting to 20 to extend her reach to 100 in one or two sessions. Keep it in the comfort zone. Try to maintain a steady cadence.

The Egyptian Zero Egyptian Counting Addition Subtraction ... Egyptian Fractions EYPTIAN COUNTING WITH HEIROGLYPHS These are the basic glyphs (symbols) used in Egypt for counting over 4000 years ago: Writing an integer consists of writing the number (from to 9) of the proper symbols to represent the integer. Thus, There is also a glyph which can translated as "equals" and a compact way of writing large glyphs, as shown below on the right, for two ways 35: in early Egypt Addition and subtraction were simple processes using the counting glyphs . To add two numbers, collect all symbols of similar type and replace a ten of one type by one of the next higher order. For example, adding 35 and 17: add Subtraction is a reversal of the process, if necessary replace a higher, so subtract Multiplication and Division Multiplication and Division were also simple processes using the counting glyphs . To multiply two numbers, all you needed to understand was the double or the half of an integer; i.e., the 2 times table.

Some of the main open problems concern the equidistribution of all eigenstates in phase space (quantum unique ergodicity) and the statistical distributions of the energy levels. The workshop will focus on the study of quantum systems in a natural number-theoretic setting, which have provided ground for the most recent advances towards the solutions of many outstanding problems in quantum chaos.

BROWSE ALPHABETICALLY LEVEL: Elementary Advanced Both INCLUDE TOPICS: Basic Math Algebra Analysis Biography Calculus Comp Sci Discrete Economics Foundations Geometry Graph Thry History Number Thry Physics Statistics Topology Trigonometry The Fundamental Theorem of Arithmetic et us begin by noticing that, in a certain sense, there are two kinds of natural number : composite numbers, and prime numbers. Composite numbers are numbers we get by multiplying together other numbers. For example, We say that 2 and 3 are factors of 6 (or, equivalently, that they are divisors of 6). Some numbers, however, have no factors other than themselves and one. Such numbers are called prime , and there are infinitely many of these. The Fundamental Theorem of Arithmetic (FTA) tells us something important about the relationship between composite numbers and prime numbers. It is usually stated as follows: Every natural number is either prime or can be uniquely factored as a product of primes in a unique way. unique.
